ABSTRACT

BACKGROUND: Breast lymphomas are a rare group of malignancies that are further subdivided into primary and secondary. AIMS: To study the pathological and clinical course of breast lymphomas. MATERIALS AND METHODS: This is a retrospective analysis of patients treated at our institute over a period of 4.5 years from September 2018 to February 2023. The details of all the patients diagnosed with breast lymphoma were reviewed and analysed for the histomorphological, immunohistochemical, clinical, and treatment details. Appropriate statistical analysis including Kaplan-Meier methods was used. RESULTS: Out of 11 cases of breast lymphoma, five were primary and six were secondary. It was seen predominantly in females (82%) and the age range was 31 to 73 years. Diffuse large B cell lymphoma (DLBCL) was the predominant morphology (73%), along with single rare cases of ALK-negative anaplastic large cell lymphoma, Burkitt lymphoma, and small lymphocytic lymphoma. The treatment details were analyzed for 7 patients. The median follow-up was 28 months. Rituximab along with CHOP regimen or its variants was commonly used as first-line treatment with initial response rates of 71%. The median progression-free survival was 5 months. The median overall survival was 15 months. CONCLUSION: Lymphomas of the breast are rare but it is crucial to differentiate them from the commoner breast carcinomas as the treatment and prognosis vary vastly.

ABSTRACT

ABSTRACT: We describe the 18F-fluorodeoxyglucose positron emission tomography/contrast enhanced computed tomography (FDG PET/CECT) images of a 63-year-old male who complained of back pain and was suspected of multiple myeloma based on magnetic resonance imaging. PET/CECT suggested the FDG avid lesion involving prostate, accompanied by multiple lytic skeletal lesions with no evidence to suggest other possible primary site. A bone marrow biopsy suggested a metastatic adenocarcinoma of primary prostatic origin. Post anti-androgen therapy follow-up FDG PET/CT revealed reductions in the metabolic activities and soft tissue components of most of the metastatic skeletal lesions. These images highlight the possible indication of FDG PET/CT in evaluation of prostatic malignancy in era of 68Ga-PSMA.

ABSTRACT

Introduction: Biologic aggressiveness of OSCC (Oral Cavity Squamous Cell Carcinoma), has intrigued research in various prognosticating histopathological markers over past few decades. DOI (Depth of Invasion) is one such histopathological factor which affects outcomes and was included in the AJCC 8th edition TNM staging. Pattern of Invasion (POI) has been widely reported as an adverse prognostic factor associated with higher locoregional failure and poor prognosis. However, these factors are not utilized for treatment decision making and for outcome assessment. Materials and methods: This is a retrospective analysis of 320 patients with OSCC who underwent treatment, from October 2018-February 2020. Clinic demographic details were extracted from electronic medical records. Univariate and multivariate analysis was done for the parameters. WPOI (Worst Pattern of Invasion) was correlated with all histopathological prognostic factors. Survival analysis was done using Kaplan Meier for WPOI type's I-V. DFS (Disease free Survival) was evaluated for different grades of WPOI. Results: We analyzed the results comparing, early and advanced T (Tumor) stages, cohesive WPOI I-III, non-cohesive WPOI IV-V. Univariate analysis showed a significant association of T-stage (p = 0.001), N (Nodal) -stage (p = 0.002), DOI (p = 0.008), PNI (Peri-neural invasion) (0.001) and Tumor differentiation Grade (p = 0.001). On multivariate analysis, non-cohesive WPOI (IV & V) showed significant association with grade, PNI, DOI (0.002, 0.033 & 0.033 respectively). Non-cohesive WPOI had significantly higher locoregional failures and short DFS. Conclusion: Presence of invasive WPOI is associated with advanced T stage, poor differentiation, PNI, greater depth of invasion, and higher chances of nodal metastasis. WPOI is associated with poor DFS, treatment intensification in early stage disease with WPOI type IV & V may improve survival.

ABSTRACT

Common presentation of primary gallbladder carcinoma is with abdominal pain, or it may be detected incidentally in postcholecystectomy specimen for cholelithiasis. Primary gallbladder carcinoma spreads to adjacent hepatic parenchyma and locoregional nodes. Lung is a common extra-abdominal site, with other sites being relatively rare. We report a case of primary gallbladder carcinoma, which presented with elbow swelling in the absence of locoregional nodal spread detected on whole-body F-FDG PET/contrast-enhanced CT at initial evaluation.

ABSTRACT

Background: Pelvic (non-uterine) high-grade serous carcinomas (PHGSC) including ovarian, tubal and primary peritoneal serous carcinomas have increased death: incidence ratio due to presentation at advanced stage, rapid progression, poor prognosis and high morbidity. Ambiguity regarding their pathogenesis and lack of a proper screening method is the cause of their late detection and high fatality rate. This study was undertaken to assess the fallopian tube for the presence of precursor lesions in pelvic serous carcinoma. Methods: This was a prospective case-control study carried out in a tertiary care center. Consecutive specimens of 55 cases of pelvic high-grade serous carcinoma and 41 controls inclusive of 21 low-grade serous carcinoma, 10 benign adnexal masses and 10 normal adnexa were included in the study. Both side fallopian tubes in each case were subjected to histopathological examination and p53, Ki67 immunohistochemistry. Results: There were 55 cases of PHGSC comprising of 50 cases of ovarian HGSC, two cases of primary peritoneal carcinoma (PPC) and three cases of tubal carcinoma. Serous tubal intraepithelial carcinoma (STIC) was detected in 14 cases (28%), p53 signature in 13 cases (26%) and tubal intraepithelial lesion in transition in 10 cases (20%) of ovarian HGSC. One case (50%) of PPC and one (33%) case of tubal carcinoma revealed the presence of STIC. None of the controls exhibited any precursor lesion except ovarian low-grade serous carcinoma where p53 was detected in 20% of cases. Conclusion: This revelation concludes that fallopian tubes are the sites of precursors of PHGSC to a large extent. In the absence of a proper screening method of HGSC, prophylactic bilateral salpingectomy at hysterectomy for benign diseases can achieve ultimate goal of reduction in incidence of PHGSC.

ABSTRACT

Synovial sarcomas of the hand are extremely rare entities than most soft tissue sarcomas. The location at finger is further rarer than carpus of the hand. Synovial sarcoma of the hand/finger initially confused with many diagnoses such as myositis, haematoma, synovitis, tendonitis, bursitis, and other inflammatory lesions and therefore needs careful handling of the case with proper evaluation. We report a case of synovial sarcoma of the palmar surface of the right hand at interface of thumb and index finger in a 22-year-old female. The case was initially misdiagnosed as an abscess/haematoma of the finger 10 years back and treated with wide local excision. Synovial sarcoma was diagnosed on microscopic examination of excised specimen. Patient developed recurrent lesion twice locally. During first recurrence, the patient was treated with wide excision followed by radiotherapy and chemotherapy. Second recurrence was with bony destruction at the same site and below elbow amputation was performed.

ABSTRACT

Melanotic neuroectodermal tumour of infancy (MNTI) is a rare, benign but locally aggressive neoplasm of infants commonly affecting the maxilla. It can also involve other areas like skull, mandible, brain and epididymis. The tumour comprise of dual populations of cells like small, basophilic neuroblast like cells and large pigment laden epithelial cells arranged in tubular and pseudoglandular pattern. The proportion of two components varies and therefore the diagnosis can be difficult in absence of the large cells. We describe the cytologic, histologic and immunohistochemical findings in a case of MNTI involving left side orbit with frontal, temporal and parietal bones. The cytologic interpretation could be made due to the suggestive clinical and radiologic findings and detection of large epithelial pigmented cells on thorough searching. The neuroblast like cells was positive for Neuron specific enolase, large cells for HMB-45 and Pan CK. Both the cellular components were negative for desmin. This case report is presented due to its rarity and also to aid the surgical pathologists in diagnosis where the findings are not too straight forward.

ABSTRACT

Primary squamous cell carcinoma of the renal parenchyma is an extremely rare entity. The diagnosis of squamous cell carcinoma of the renal pelvis is usually unsuspected due to the rarity and inconclusive clinical and radiological features. Most of the patients are diagnosed at an advanced stage and are with poor outcome. Radical nephrectomy is the mainstay of the treatment. We reported a case of squamous cell carcinoma of the kidney in a 50-year-old female who presented with the right sided abdomen pain. The patient was treated with radical nephrectomy.
